D-Brane Scattering of N=2 Strings
K. Juenemann, Bernd Spendig
TL;DR
This paper calculates scattering amplitudes of N=2 strings off D-branes, revealing the presence of massive poles in some cases, which differ from the standard N=2 spectrum.
Contribution
It provides detailed amplitude calculations for N=2 strings interacting with various D-branes, uncovering new massive states in the scattering spectrum.
Findings
Massive poles appear in the scattering spectrum for certain D-branes.
Amplitudes <cc> and <occ> are explicitly computed for different D-brane types.
Some D-branes exhibit features not present in the ordinary N=2 string spectrum.
Abstract
The amplitudes for emission and scattering of N=2 strings off D-branes are calculated. We consider in detail the amplitudes <cc> and <occ> for the different types of D-branes. For some D-branes we find massive poles in the scattering spectrum that are absent in the ordinary N=2 spectrum.
